Dear Sir or Madam,

We would like to present the catalogue of mechanical seals of ANGA, in which we introduce our standard products and the selection of customized products. We provide the basic information needed for correct mechanical seal selection. The selection is based upon the sealed medium, operating conditions and the kind of equipment in which a given seal has to be assembled.

This catalogue may be useful to end users, designers and maintenance staff of companies manufacturing and operating pumps, mixers, agitators, reactors, high rotational speed gears, fans and other machines with rotating shafts which require efficient and reliable mechanical seals.

IntroductionTable of contents

This document has both informal and practical character. As in any case of this kind, a seal user can use his knowledge and experience for the seal selection.However, in case of any doubts, ANGA Uszczelnienia Mechaniczne Sp. z o.o. (ANGA) provides information and advice, especially if operating conditions of the seal are dangerous for the personnel and the environment.All rights concerning this issue and source materials are reserved, regardless of information carrier, on which they exist. Copying, reproduction or dissemination in any form, in whole or in part, of information contained in this publication or in its source materials without ANGA’s written approval is prohibited. ANGA reserves the right to change the design or specification of its products without prior notice. Products manufactured by ANGA are patent protected.

* NOTE:ANGA can guarantee the quality of its products only after a detailed analysis of the operating conditions in which our products will operate. Therefore, in any case, we recommend that you should contact our specialists who will confirm the possibility of using the ANGA product in each case.In particular, it should be noted that due to interaction, the extreme values of individual operating parameters cannot be applied at the same time. In addition, the wor-king conditions of particular products depend on the materials used, the characteristics of operation of the device, the diameter of the shaft and characteristics of the sealed medium.All technical data shown in this catalog are based on experiences and researches conducted by our company. However, mechanical seals can be used in many diffe-rent conditions, which means that the catalog data are given only for informative purposes.

Other mechanical seals

IDZ-L.090 is a special mechanical seal designed for sealing shafts of very large kneading reactors, which knead very viscous adhesive masses. The design of kneaders, their large size and the specificity of processes require the use of the split seal, which will be working with a viscous medium and will be durable and easy to install.

Auxiliary installationsApart from a wide range of mechanical seals offered by ANGA, we also provide our Customers with auxiliary installations,without which some applications of seals or effective and reliable operation of seals would not be possible. ANGA offersauxiliary installations designed according to EN ISO 21049 (API 682).

The most popular are auxiliary installations in accordance with API Plans 23, 52, 53A and 74, but on customer’s request itis possible to provide installation according to other API Plans. Installations and their components are selected individuallyin accordance with the requirements of the Customer and the characteristics of the sealed process.

Below we present examples of the most common installations.

Plan 52 – the system is an unpressurized buffer liquid installation, comprising a buffer liquid tank, necessa-ry connectors, valves, control and measuring equip-ment. The installation is connected to a double seal. During normal operation, the buffer liquid circulation is forced and maintained by the internal pumping ring of the seal. The tank is normally vented continu-ously to the gas recovery system and the pressure in it is lower than the pressure in the stuffing box.

Plan 53A – the system is a pressure barrier liquid installation, comprising a barrier liquid tank, a manual pump for barrier liqu-id refilling, necessary connectors, valves, control and measuring equipment. The installation is connected to a double seal. Du-ring normal operation, the barrier liquid circulation is forced andmaintained by the internal pumping ring of the seal. Pressure inthe tank is higher than the pressure in the gland box and thus, the sealed medium is fully hermetic, and only a slight amount of the barrier liquid goes into the product and out into the at-mosphere. Pressure in the tank is maintained by connecting an external pressure source, e.g., compressed nitrogen.

Auxiliary installations

Plan 53B - It is an external system of the barrier fluid, which is under a higher pressure than the pressure in the stuffing box (sealing chamber). The circulation of the barrier liquid is forced by an internal device of a seal.The pressure of the barrier fluid is kept by a diaphragm accumulator tank. The use of the accumulator tank prevents from gas absorption by the barrier liquid and enables the operation of the system at high pressure. The system is monitored by the decrease of pressure of the barrier liquid, caused by the leakage of the barrier liquid through internal and external seals. The pressure decrease is corrected by refilling of the barrier liquid.
